Altogether, these findings suggest administering ibrutinib before leukapheresis may modify T-cell characteristics in the collected material, thereby improving final CAR T-cell product quality and clinical outcomes for patients with R/R LBLC treated with tisagenlecleucel. This trial was registered at www.clinicaltrials.gov as #NCT03876028.
To investigate this clinical issue, 106 patients treated with CAR-T cell therapy using either tisagenlecleucel, lisocabtagene maraleucel or axicabtagene ciloleucel for r/r DLBCL at our institution were retrospectively analyzed. Multivariate analysis revealed that CD5 expression was unfavorably associated with PFS and OS. Together, these data suggest that CD5 expression has a negative impact on outcomes after CAR-T cell therapy.
